Synopsis

This anime focuses on Kazama Mana, the main character of Yakin Byoto 2. She is an intern works for a sanatorium as an intern nurse. Mana looks up to Nightingale, and she want to be an angel in white like her. But, Mizukawa Wataru, the patient whose days are numbered, says to her that there’s no angel and begins to make her a sex game.

Very nice hentai that you gonna enjoy watch! Because of graphic and animation like the scenes obviously if you come to watch an anime hentai you want to get more excited than that you are so this have the scenes and situations.
It's something bizarre but when you are excited you probably don't gonna care for that.
I repeat you must watch this when you are very excited or bizarre sex is okay for you.

Short spoiler-free review for this MAL entry:
Following it’s predecessor with the same quality in art, music, voice acting and presentation, this time the story is more apparent. Still mostly character driven, this leading female’s feelings are a tad more normal, convincingly portraying sadness and fear. The brutal, depressing story features a lot of extreme scat, which heavily downgrades the otherwise completely sexy scenes. While not as succesful in fascinating the viewer as the last time, the poetry of the story is beautifully conveyed, even featuring a real animated opening.
Score: 6/10

(Disclaimer)
(Nanase Ren, Kazama Mana and Yagami Yuu should be viewed as one series
in my opinion, but MAL doesn’t always agree with me. They are based on the same eroge series, they share similar opening displays, have the same opening song AND ending song, and are presented as a regular threepart hentai OVA, with a coherent style throughout. They are clearly one single anime, and because of this I would like to review these entries as one. I am working on that and will hopefully edit this review in the future to adress it.)

Kazama Mana is a really great hentai (despising the scat scenes) and I'm gonna list the reasons why this hentai is great.

Story: 9/10. Kazama tries to take care of Wataru (the sick patient) but she gets into bizzare sex scenes. ex. (bondage, fellatio/blowjob, vibrated dildos/vibrated sex toys, scat (shitting), losing the virginity, peeing, insane, brutal ripping, nipple vibrator scene, "the shitting scene when she thought that she was a angel") It is kinda sad but it's fine. They had a bad/"good" ending.

Art: 8/10. I love Murakami Teruaki.

Sound: 7/10. moaning, forced screaming.

Characters: 7/10. Kazama was sterotyped in the beginning and middle-end thanks to the fucking men
that wanted to fuck Kazama. Wataru was kinda annoying. The short blue-haired doctor was stereotyped and fine

Enjoyment: 9/10. moaning. but the ending made me feel like i wanted to see more Kazama Mana.
